Document Type and Number:

WIPO Patent Application WO2001062700

Kind Code:

A3

Abstract:

A method for adjusting the concentration of starting materials, comprising adjusting the starting material concentration in a gas fed to a reactor in a gas phase contact reaction process having a recycling system, wherein the concentration of a starting material in a gas in the process is measured, the starting material is fed by setting the feed amount of the starting material newly added to the process based on the measured value, and thereby the starting material concentration in the gas fed to the reactor is controlled; and a method for controlling a reaction process using the above-described adjusting method.
